Prefixes and Suffixes

There are many prefixes and suffixes in English. What I posted here is just a few of them. You might need to consult your dictionary to know other kinds of prefixes and suffixes.

If you put a certain prefix to a root word, it will change the meaning of the word. For example, if you put the prefix in- before the root word ‘active’, it means not active.

To change the function of the root word, just add a suffix at the end of the word. For example, if you place the suffix -er at the end of the verb ‘compute’, so now it becomes ‘computer’ and functions as a noun.
